Constructor & Destructor Documentation

Draw()

sf::Draw::Draw

(

)

Default constructor.

Member Function Documentation

gaugeBarPanel()

void sf::Draw::gaugeBarPanel	(	QWidget *	widget,
		QPaintEvent *	event,
		double	progress,
		const QString &	str = {}
	)

Draws a horizontal gauge rectangle inside a styled panel.

Parameters

widget	Widget which send this event.
event	Paint event send from the widget.
progress	Progress value for drawing the bar. When negative only the string is drawn.
str	Text put in a rectangle in the middle. By default, the percentage is drawn.

gridLines()

bool sf::Draw::gridLines	(	QPainter &	painter,
		EGridOrientation	go,
		const QColor &	color,
		const QRect &	bounds,
		double	start,
		double	stop,
		unsigned	digits
	)		const

Draws the lines in the graph as the ruler ticks.

Parameters

painter	Painter context.
go	Orientation.
color	Color of the grid lines.
bounds	area boundaries for the ruler.
start	Start value of grid lines.
stop	Stop value of grid lines.
digits	To make the grid correspond with the ruler when vertical.

Returns

True on success false in case of an exception.

ruler()

bool sf::Draw::ruler	(	QPainter &	painter,
		ERulerOrientation	ro,
		const QColor &	color,
		const QColor &	font_color,
		const QRect &	bounds,
		const QRect &	area,
		double	start,
		double	stop,
		int	digits,
		const QString &	unit
	)		const

Draws a ruler for example around a graph.

Parameters

painter	Painter context.
ro	Orientation.
color	Color for the ticks.
font_color	Color of the texts.
bounds	Boundaries for the ruler.
area	area available to paint texts on.
start	Start value of ruler.
stop	Stop value of ruler.
digits	Amount of significant digits or resolution of the printed values.
unit	unit string.

Returns

True on success false in case of an exception.

textCross()

bool sf::Draw::textCross	(	QPainter &	painter,
		const QRect &	bounds,
		const QString &	text,
		const QColor &	color
	)

Draws a cross with text rectangle in the middle.

Parameters

painter	Painter context.
bounds	area boundaries for the ruler.
text	Text put in a rectangle in the middle.
color	Color of the cross and text.

Returns

True on success false in case of an exception.
